FROM MTV NEWS: Wednesday night on "Late Night With Jimmy Fallon," Microsoft's Kudo Tsunoda demonstrated "Project Natal." Expected to launch in 2010, "Project Natal" features a camera that hooks up to your Xbox 360, letting you play games just by moving your body — no controller needed.

Tsunoda began the demonstration with "Ricochet," a game that is almost like virtual handball. A 3-D representation of yourself will appear onscreen, and by swinging your arms and legs in the air, you can bat back a ball that breaks digital blocks at the end of a hallway.
